Hi the taxco pendant is by JAB, If anybody knows of this person, please let me know, also, what is the Aztec doing? It weighs 49.5grams. It is beautiful, inset with turquoise chips? And the Indian is copper? and brass? I think this is from the 1950's? The ring is 23 grams and no markings, but tested 925. I really like both of these.
